The Lowdown
Alright, grab your board, let’s see what we’ve got for Jaconé over the next couple of weeks.
Alright, the start of the week is a write-off, I’m not even going to sugarcoat it. Sunday the 6th is a total mess with that southerly wind and short-period, choppy slop. Don’t bother paddling out. We need to wait until Monday morning, the 7th, for things to turn around.
And turn around they do! Monday the 7th is your first real chance. The swell picks up to a solid 8 ft from the south, with a period of 10 seconds, and here’s the kicker – it’s completely glassy. The combined wave energy is strong (1390), and for experienced surfers, this is a proper session. The afternoon holds a clean 8 ft with a light cross-offshore breeze, keeping things tidy.
Tuesday the 8th is still very good. A clean 5 ft south swell with a gentle offshore wind. Wednesday and Thursday look smaller, but that glassy, clean morning surf will be tempting for a longboard or a funboard. The swell drops but the quality remains with light winds.
The real standout, the one you’ve got to circle on your calendar, is Saturday the 19th. We’re looking at a very long-period south groundswell with a period of 18 seconds and a height of 4 ft. The energy is massive at 1043, and it’s glassy in the morning. This is a classic Jaconé day – that long-period south swell will wrap in beautifully. The swell direction from the south is spot-on for the break. The only thing to keep in mind with a period that long is it might wall up a bit at the beach breaks, but the points and reefs will be firing. Keep an eye on the crowd situation too, as it can get busy.
Then, Sunday the 20th keeps the good times rolling with a clean 7 ft south swell and a period of 15 seconds under offshore winds in the morning. That’s another top-tier session for the experienced crew.
Beyond that, Monday the 21st still has some nice, clean leftover swell. The rest of the second week is quieter, with smaller swells and more variable winds. The water temp is sitting at 72°F which is pretty average for this time of year, so no surprises there.
So, for the best of the best, lock in Saturday the 19th and Sunday the 20th. Monday the 7th is your early-week redemption. The rest of the time, keep an eye on those morning glass-offs for the smaller, cleaner waves.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
